The facility is operated by Circle K Stores Inc., as a convenience store, gas station, and car wash. The current UST system consists of one 20,000-gallon gasoline UST, one 8,000-gallon gasoline UST, one 3,000-gallon gasoline UST, and one 3,000-gallon diesel UST. On July 17, 2023, ATC conducted a groundwater monitoring event at the Circle K Store No. 2723940, which included gauging the site wells and collecting groundwater samples for laboratory analysis. These activities were conducted in accordance with the Pre-Approval Task Authorization (PATA) number 36286-19, approved on May 22, 2023 Based on the field activities and laboratory analysis discussed herein, ATC offers the following findings:  An estimated 123.68 pounds (22.95 equivalent gallons) of petroleum hydrocarbons were recovered as vapor during the MMPE event. The MMPE event generated approximately 5,456 gallons of petroleum impacted groundwater.  ATC gauged and sampled monitoring wells MW-1A, MW-3, MW-4, MW-6, MW-10, MW- 11, MW-12, MW-13, MW-14, MW-15, MW-16, DW-1, DW-2, DW-3.  LNAPL was not detected during the July 2023 sampling event.  Methyl-Tert-Butyl-Ether (MTBE and Tert-butyl Alcohol (TBA) were detected above the North Carolina Gross Contamination Levels for Groundwater Levels (GCLs) in the samples collected from monitoring well MW-11.  Monitoring wells MW-1A, MW-4, MW-10, MW-11, MW-12, MW-14, MW-15, MW-16, and DW-1 also contained two or more petroleum constituents at concentrations above 2L Standards.  Monitoring wells MW-3, MW-6, MW-13, DW-2 and DW-3 did not contain detectable concentrations of VOCs.  Groundwater flows to the northwest and to the southeast from a high centered at MW-1A.  The concentration of MTBE in DW-1 indicates that the vertical extent of the contaminant plume has not been defined at depth in that area. Subsequent to the MMPE event groundwater analytical results indicate that the contaminant plume is generally stable, and LNAPL was not detected in MW-16. The constituent concentrations reported in MW-16 were reduced compared to the June 2022 sampling event. ATC recommends an additional groundwater monitoring event to monitor the stability of the constituent concentrations and determine if the presence of residual LNAPL has been addressed. Monitoring Report Circle K 2723940 Incident No. 40437 Page 2 2.0 SITE CHARACTERIZATION AND HISTORY 2.1 Area of Investigation The site is located at 10409 Mallard Creek Road in Charlotte, Mecklenburg County, North Carolina, and is currently an active convenience store and gas station. The site is developed with one single-story building, an automatic car wash, four active underground storage tanks (USTs), and one fuel canopy with five dispenser islands. The UST system consists of one 20,000-gallon gasoline UST, one 8,000-gallon gasoline UST, one 3,000-gallon gasoline UST, and one 3,000- gallon diesel UST. According to information obtained from the NCDEQ UST Registry Database, the existing USTs were installed in August 1997. Summaries of UST system and owner/operator information is included in Table 1 and Table 2. A site vicinity map with topographic features is included as Figure 1. Site features are illustrated on Figure 2. Immediately surrounding properties are developed for commercial use. Prosperity Church Road adjoins and provides site access to the north, Mallard Creek Road adjoins and provides site access to the south, and the two roads intersect to the east. Table 3 summarizes adjoining property owners/occupants. 2.2 Receptor Survey A receptor survey was conducted by a previous consultant to identify water supply wells, surface water bodies, and other potential receptors within 1,500-feet of the source area. During the receptor survey, one active water supply well (WSW-1) was identified approximately 915-feet northwest of the source area and was reportedly utilized for potable drinking water. A second water supply well was identified over 1,000 feet away, but the well status was unknown. Table 4 summarizes water supply well and potential receptor information. Locations of potential receptors are illustrated on Figure 3. The site is not located in a wellhead protection area or within the Coastal Plain Physiographic province. Underground utilities are present on site, however they do not intersect the water table. 2.3 Site History Incident # 36286 As part of a preliminary Phase II ESA conducted prior to a property transaction, SEI Environmental (SEI) collected groundwater samples from observation wells installed in the UST pit. The groundwater samples contained petroleum constituents at concentrations in excess of 2L Standards, and a release was reported to the UST Section on April 2, 2007. SEI conducted Site Check and Site Check Addendum investigations in June and August 2007. Soil samples collected from soil borings advanced around the perimeter of the four UST systems, the sumps of each UST, and the product lines and dispensers revealed gasoline range - total petroleum hydrocarbons (TPH-GRO) in two of the soil samples advanced around the perimeter of the UST systems. Groundwater samples collected from the UST pit observation wells indicated concentrations of petroleum constituents exceeding the 2L Standards but below the Gross Monitoring Report Circle K 2723940 Incident No. 40437 Page 3 Contamination Levels (GCLs). UST, line, and leak detector integrity testing was completed on March 31, 2007, and all components passed their respective testing method requirements. SEI concluded in their August 30, 2007, report that the source of the release was likely associated with the condition of entry boots for the regular gasoline UST sump and the premium gasoline UST sump. In January 2008, Withers Ravenel (WR) completed Phase I and Phase II LSAs. One active water supply well was identified within 1,000 feet of the site. Monitoring well MW-1, installed during a previous phase of investigation, was determined to be improperly constructed, and was replaced by WR. Monitoring wells MW-1A, MW-2, MW-3, and MW-4, were installed and sampled. Laboratory analysis indicated monitoring well MW-1A and MW-4 contained concentrations of petroleum constituents exceeding the 2L Standards but below GCLs. In August 2009, WR sampled the four monitoring wells. The laboratory analytical results detected concentrations of MTBE exceeding 2L Standards in monitoring wells MW-1A and MW-4. Di- isopropyl ether was detected above 2L Standards in monitoring well MW-1A. All concentrations were below their respective GCLs. Comprehensive Site Assessment (CSA) activities were conducted in late 2009. Soil samples were collected from three sides of the UST pit. One soil sample, installed in the general area of SB-9 advanced by SEI during the Site Checks, contained MTBE above the soil- to-groundwater MSCC. Five additional Type II monitoring wells (MW-5 through MW-9) and one Type III monitoring well (DW-1) were installed and sampled in addition to the existing monitoring wells. The laboratory analytical results detected concentrations of MTBE (MW- 1A, MW-3, MW-4, and DW-1), C5-C8 Aliphatics (MW-1A and DW-1), benzene (MW-1A), and di-isopropyl ether (MW-1A and DW-1) exceeding their established 2L Standards in the monitoring wells; however, all concentrations were below their respective GCLs. Groundwater monitoring events were conducted by WR in October 2010, April 2011, and September 2011. Groundwater samples were collected from each of the ten onsite monitoring wells for analysis by EPA Methods 6200B, 625, and MADEP VPH/EPH. For all three monitoring events, laboratory analytical results detected concentrations of MTBE above 2L Standards in MW-1A, MW-3, MW-4, and DW-1; C5-C8 aliphatics detected above 2L Standards in MW-1A and DW-1; and DW-1 had 2L exceedances of di-isopropyl ether and bis(2-ethyhexyl)phthalate. Monitoring well MW-1A had 2L exceedances of C9-C22 aromatics and benzene in October 2011, and benzene in April 2011. Detected petroleum constituents were below applicable GCLs for all sampling events. In February 2012, groundwater samples were collected from each of the ten onsite wells for analysis by EPA Methods 6200B and MADEP VPH/EPH. Laboratory analyses indicated concentrations of MTBE equal to the GCL in monitoring well DW-1, and above 2L Standards in monitoring wells MW-1A and MW-4. Concentrations of C5-C8 aliphatics were also above the 2L Standard in MW-1A and DW-1, and DW-1 also contained di- isopropyl ether over the 2L Standard. Monitoring Report Circle K 2723940 Incident No. 40437 Page 4 In November 2012, WR installed monitoring wells MW-10, MW-11, and DW-2 through DW-4, and conducted a comprehensive groundwater sampling event. Concentrations of C5-C8 aliphatics were detected above 2L Standards in monitoring wells MW-1A, MW-10, and DW-1. MTBE exceedances were detected in MW-1, MW-1A, MW-3, MW-4, MW-10, MW-11, DW-1, and DW-2. In September 2013, WR conducted a comprehensive groundwater sampling event. MTBE exceeded the GCL of 20,000 µg/L in wells DW-1 and MW-1A. Multiple monitoring wells also contained one or more of the following contaminants at concentrations above their respective 2L Standards: C5-C8 aliphatics, benzene, IPE, MTBE, and naphthalene. WR and Advanced Environmental Services completed a 96-hour MMPE event from August 26 – 30, 2013, on monitoring wells MW-1A, MW-10, and DW-1. A total of 1,604- gallons of impacted groundwater and 15.87-gallons of VOC’s as vapor were removed during the event. A Corrective Action Plan, prepared by WR, proposed the installation of two shallow and two deep screened ISOC Oxygen Diffusion wells in the area of MW-10 and DW-1 to address the MTBE plume. The CAP was approved by NCDEQ in a NORR letter dated June 20, 2014, but was put on hold following a new release discovered in December 2014. Incident # 40437 In December 2014, gasoline product was observed discharging from the secondary containment piping in the STP sump associated with the 20,000-gallon gasoline UST. Line tightness testing revealed a leak in the flex connector. LNAPL assessment and groundwater sampling activities were conducted in January 2015. MTBE exceeded the GCL in well MW-10, and the 2L Standard in wells MW-3, MW-4, MW-11, DW-1, and DW- 2. Monitoring well MW-10 also contained Di-Isopropyl Ether, Toluene, and Total Xylenes above 2L Standards. Initial Abatement Actions completed in early 2015 involved soil sampling during the installation of five Type II monitoring wells (MW-12 through MW-16), and four AFVR events. Shallow soil samples contained benzene above the MSCC in three of the sampled locations. Monitoring wells MW-12, MW-13, and MW-16 contained measurable LNAPL. MTBE exceeded the GCL in well MW-14, which was attributed to the previous release, as MTBE had reportedly been phased out several years prior. Four AFVR events completed in January and February 2015 removed a combined total of 237.27 pounds (38.45 equivalent gallons) of gasoline as vapor, 7,970 gallons of impacted groundwater, and 9 gallons of free phase product. A 96-hour MMPE event conducted in February 2016, removed 108.59 pounds (17.65 gallons) of VOCs as vapor, and 2,735 gallons of impacted groundwater. The subsequent groundwater monitoring event detected concentrations of MTBE exceeding the GCL in Monitoring Report Circle K 2723940 Incident No. 40437 Page 5 monitoring wells DW-1, MW-10, and MW-14. Multiple monitoring wells contained VOCs exceeding 2L Standards. Additional groundwater monitoring events were conducted in November 2016, April 2017, November 2017, April 2018, October 2018, May 2019, December 2019, and June 2020. Monitoring well MW-10 consistently contained MTBE above the GCL. Multiple other wells contained additional VOCs exceeding 2L Standards. In June 2020, WR also placed Provectus Oxygen Releasing Socks (ORS) in monitoring wells MW-10 and MW- 14. WR recommended semi-annual sampling of select monitoring wells until GCL exceedances are reduced by biodegradation. In January 2021, ATC conducted a limited groundwater monitoring event at the Circle K Store No. 2723940, gauged the specified site wells and collected groundwater samples for laboratory analysis. LNAPL was not measured or observed in the gauged and sampled monitoring wells. Volatile organic compounds (VOCs) were not detected above Gross Contamination Levels (GCLs) in the sampled monitoring wells. Methyl-tert-butyl-ether (MTBE) was detected above North Carolina Groundwater Quality Standards according to 15A NCAC 2L .0202 Standards (2L Standards) in the samples collected from monitoring wells MW-1A, MW-10, MW-14, MW-16, DW- 1, and DW-2. Monitoring wells MW-1A, MW-10, MW-16, DW-1, and DW-2 also contained two or more petroleum constituents at concentrations above 2L Standards. Oxygenate tert-butyl alcohol (TBA) was detected above 2L Standards in monitoring wells MW-10, MW-16, DW-1, and DW-2. Monitoring well DW-3 did not contain detectable concentrations of VOCs. Petroleum constituents were not detected in the water sample collected from water supply well WSW-1. In June 2022, ATC conducted a groundwater monitoring event at the Circle K Store No. 2723940. LNAPL was not measured or observed in the gauged and sampled monitoring wells. MTBE was detected above 2L Standards in the samples collected from monitoring wells MW-4, MW-10, MW- 11, MW-12, MW-14, MW-15, MW-16, and DW-1.Oxygenate tert-butyl alcohol (TBA) was detected above the North Carolina Gross Contamination Levels for Groundwater (GCL) in MW-10. TBA was also detected above the above the North Carolina Groundwater Quality Standards according to 15A NCAC 2L .0202 Standards (2L Standards) in the samples collected from monitoring wells MW-4, MW-11, MW-12, MW-14, and DW-1.Monitoring wells MW-1A, MW-4, MW-10, MW-11, MW-12, MW-14, MW-15, MW-16, and DW-1 also contained two or more petroleum constituents at concentrations above 2L Standards. Based on the findings of this report, it appears that constituents are generally decreasing in monitoring wells MW-1A, MW-3, MW-13, MW-4 and MW- 15. Constituent concentrations are generally stable in monitoring wells MW-4, MW-11, and MW- 12. On December 8, 2022, ATC conducted a groundwater sampling event. Monitoring wells MW-1A, MW-3, MW-4, MW-6, MW-10, MW-11, MW-12, MW-13, MW-14, MW-15, and DW-1 through DW- 3 were gauged for depth to water and total well depth, with an electronic water level indicator. On December 8, 2022, ATC gauged and sampled monitoring wells MW-1A, MW-3, MW-4, MW- 6, MW-10, MW-11, MW-12, MW-13, MW-14, MW-15, DW-1, DW-2, DW-3. ATC sampled monitoring wells MW-1A, MW-3, MW-4, MW-6, MW-10, MW-11, MW-12, MW-13, MW-14, MW- Monitoring Report Circle K 2723940 Incident No. 40437 Page 6 15, DW-1, DW-2, DW-3. LNAPL was measured at a thickness of 0.08 feet in MW-16 therefore it was not sampled. Methyl-Tert-Butyl-Ether (MTBE and Tert-butyl Alcohol (TBA) were detected above the North Carolina Gross Contamination Levels for Groundwater Levels (GCLs) in the samples collected from monitoring wells MW-11 and DW-1. Monitoring wells MW-1A, MW-4, MW- 10, MW-11, MW-12, MW-14, MW-15, MW-16, and DW-1 also contained two or more petroleum constituents at concentrations above 2L Standards. Monitoring wells MW-3, MW-6, MW-13, and DW-3 did not contain detectable concentrations of VOCs. 3.0 GEOLOGIC FRAMEWORK According to the 1985 “Geologic Map of North Carolina”, the site is located in the Charlotte Belt of the Piedmont Physiographic Province. Subsurface lithology in the region consists of metamorphosed, inter-bedded tuffs and flow rock of felsic to mafic composition. Granitic intrusions are also common in the area. The soils are typically saprolitic and are formed by in-place weathering of bedrock and the subsequent breakdown of associated minerals. Surficial soils reported by previous consultants during drilling activities consisted of red silt clay to approximately 15-feet Below Ground Surface (BGS) and partially weathered rock (PWR) from 15-feet BGS to at least 20-feet BGS. 4.0 MOBILE MULTI-PHASE EXTRACTION EVENT From June 19 to June 23, 2023, Zava Industrial, Inc. (Zava) performed 96-hour MMPE event. ATC personnel provided onsite supervision for event set-up and break-down. Monitoring wells MW-11, MW-12 and MW-16 were utilized as target extraction wells for the 96-hour MMPE event. Prior to starting and upon completion of the MMPE event, extraction wells were gauged for liquid levels. LNAPL was not detected in the wells during pre- or post-MMPE well gauging. During MMPE activities, a liquid ring vacuum pump unit is plumbed to the designated extraction point, and a drop pipe is extended into the well through an airtight seal at the top of the well casing and into the water column. Throughout the MMPE process, a cone of depression forms around the designated recovery point by drawing down the groundwater surface levels, thus causing impacted water surrounding the recovery point to be extracted. Petroleum-impacted soil vapor within the cone of depression and the overlying vadose zone is removed as part of the MMPE extraction process. The 96-hour AS/MMPE event began on June 19, 2023, and ended on June 23, 2023. The effluent air stream was monitored for temperature, velocity, relative humidity, and organic vapor concentrations on a daily basis. Calculated effluent airflow rates and the vapor concentration readings from the vacuum truck indicated that an estimated 123.68 pounds (22.95 equivalent gallons) of petroleum hydrocarbons were recovered as vapor during the MMPE event. The MMPE event generated approximately 5,456 gallons of petroleum impacted groundwater. Monitoring Report Circle K 2723940 Incident No. 40437 Page 7 A report provided by Zava, which includes monitoring data, emissions and recovery calculations, and waste disposal manifests is included in Appendix A. 5.0 SITE ASSESSMENT ACTIVITIES 5.1 Groundwater Sampling Activities On July 17, 2023, ATC conducted a groundwater sampling event. monitoring wells MW-1A, MW- 3, MW-4, MW-6, MW-10, MW-11, MW-12, MW-13, MW-14, MW-15, MW-16 and DW-1 through DW-3 were gauged for depth to water and total well depth with an electronic water level indicator. Depths to groundwater in the shallow monitoring wells ranged from 7.64-feet below top of casing (ft-BTOC) in MW-4, to 12.25 ft-BTOC in MW-11. Shallow groundwater flow was interpreted to trend generally to the northeast as shown on Figure 4. The screened intervals for deep monitoring wells DW-1 through DW-3 do not intersect the water table, thus these wells were not utilized in the determination of shallow groundwater flow. Groundwater generally flows to the northwest. Type III monitoring wells DW-1 and DW-3 are both installed to 50-feet BGS and screened from 45 to 50-feet BGS and monitoring well DW-2 is installed to 80-feet BGS and screened from 70 to 80-feet BGS. Due to the difference in constructions, it is not possible to interpret potential groundwater movement deeper in the aquifer. A summary of current and historical liquid level data is included as Table 5. Groundwater samples were collected from monitoring wells MW-1A, MW-3, MW-4, MW-6, MW- 10, MW-11, MW-12, MW-13, MW-14, MW-15, MW-16, and DW-1 through DW-3. The wells were purged prior to sample collection using new, disposable polyvinyl chloride bailers or a submersible pump and clean tubing, while wearing new, disposable nitrile gloves. Purging was accomplished by removing a minimum of three well volumes or until the well was bailed dry and allowed to recharge. Field parameters were measured at the time of sampling and recorded in field books. Field notes are included as Appendix A. Groundwater samples were placed into laboratory provided sample containers, sealed and labeled, and placed into an ice-filled cooler for preservation. Following completion of sampling activities, samples were submitted under chain-of-custody protocol to Pace Analytical Services, LLC (Pace), a North Carolina certified laboratory, located in Huntersville, North Carolina. The groundwater samples were analyzed for select volatile organic compounds (VOCs) and oxygenates by Standard Method 6200B. 5.2 Groundwater Analytical Results Groundwater analytical results from samples collected are summarized as follows:  ATC sampled monitoring wells MW-1A, MW-3, MW-4, MW-6, MW-10, MW-11, MW-12, MW-13, MW-14, MW-15, MW-16 and DW-1, DW-2, DW-3. Monitoring Report Circle K 2723940 Incident No. 40437 Page 8  Methyl-Tert-Butyl-Ether (MTBE and Tert-butyl Alcohol (TBA) were detected above the North Carolina Gross Contamination Levels for Groundwater Levels (GCLs) in the samples collected from monitoring well MW-11.  Monitoring wells MW-1A, MW-4, MW-10, MW-11, MW-12, MW-14, MW-15, MW-16, and DW-1 also contained two or more petroleum constituents at concentrations above 2L Standards.  Monitoring wells MW-3, MW-6, MW-13, DW-2 and DW-3 did not contain detectable concentrations of VOCs. Summaries of the current and historical groundwater analytical data are provided in Table 6 and Table 7 Contaminants detected above 2L Standards are identified and summarized on Figure 5. The laboratory analytical report and chain-of-custody documentation is included as Appendix B. 6.0 CONCLUSIONS AND RECOMMENDATIONS From June 19 to June 23, 2023, Zava Industrial, Inc. (Zava) performed 96-hour MMPE event. On July 17, 2023, ATC conducted a groundwater monitoring event at the Circle K Store No. 2723940, which included gauging the site wells and collecting groundwater samples for laboratory analysis. These activities were conducted in accordance with the Pre-Approval Task Authorization (PATA) number 36286-19, approved on May 22, 2023 based on the field activities and laboratory analysis discussed herein, ATC offers the following findings:  An estimated 123.68 pounds (22.95 equivalent gallons) of petroleum hydrocarbons were recovered as vapor during the MMPE event. The MMPE event generated approximately 5,456 gallons of petroleum impacted groundwater.  ATC gauged and sampled monitoring wells MW-1A, MW-3, MW-4, MW-6, MW-10, MW- 11, MW-12, MW-13, MW-14, MW-15, MW-16, DW-1, DW-2, DW-3.  LNAPL was not detected during the July 2023 sampling event.  Methyl-Tert-Butyl-Ether (MTBE and Tert-butyl Alcohol (TBA) were detected above the North Carolina Gross Contamination Levels for Groundwater Levels (GCLs) in the samples collected from monitoring well MW-11.  Monitoring wells MW-1A, MW-4, MW-10, MW-11, MW-12, MW-14, MW-15, MW-16, and DW-1 also contained two or more petroleum constituents at concentrations above 2L Standards.  Monitoring wells MW-3, MW-6, MW-13, DW-2 and DW-3 did not contain detectable concentrations of VOCs.  Groundwater flows to the northwest and to the southeast from a high centered at MW-1A.  The concentration of MTBE in DW-1 indicates that the vertical extent of the contaminant plume has not been defined at depth in that area. Subsequent to the MMPE event groundwater analytical results indicate that the contaminant plume is generally stable, and LNAPL was not detected in MW-16. The constituent concentrations reported in MW-16 were reduced compared to the June 2022 sampling event. Monitoring Report Circle K 2723940 Incident No. 40437 Page 9 ATC recommends an additional groundwater monitoring event to monitor the stability of the constituent concentrations and determine if the presence of residual LNAPL has been addressed. 7.0 LIMITATIONS This report has been prepared for the exclusive use of Circle K Stores Inc. for specific application to the referenced site in Charlotte, North Carolina.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.
